Wouldn't there be ...

SPOILER alert



Wouldn't there be three pod people in the form of Elizabeth? She was replicated when she was still living with Jeffrey. She was in blue pajamas sleeping in her bed, but then there was a nude pod person formed in her yard or balcony. When Matthew rushes over there and the cops are there too, her nude pod person has disappeared.

Then she's replicated again when she, Jack, and Nancy are all camping out at Matthew's apartment. In Matthew's yard, you see a replica of him, Elizabeth, Jack and Nancy. Matthew was about to strike Elizabeth's replica with a garden hoe but can't bring himself do it. He does, however, bludgeon his own replica with the hoe. Finally, in the field near the ship. She falls asleep and is quickly transformed. We see her nude replica and then we see her again (nude!) in the pod nursery. Finally, we see one of her three incarnations at work in a lab coat. Am I missing something or would she have been cloned three times?
